If subscribing is free, you might be able to do it with Subscribe and Notify. You can create a custom Tpl chunk for Notify to use to send email to a User Group (or groups). It can contain resource field tags, but I'm not sure if you can use a TV tag in the Tpl chunk or not.
EmailResource might do it, but it's fairly old and clunky. It sends the whole resource to the user in an email. I'm pretty sure it would process any TV tags.
OK thanks Bob as ever - I will have a play.
